I've been frustrated with processing raster imagery in ArcMap ever since 8.0 came out way back when. I finally got around to making my own tool that makes clipping and mosaicking much easier and more intuitive. All the relevant info (mosaic type, extent, etc) is right there on the dialog, and most importantly, this tool works seamlessly with raster catalogs. Another nicety is that the output is a plain old TIF file with a TFW file, so that AutoCad puts the image into the right place (for some reason I could never get ArcMap to make a GeoTIFF file that AutoCad Map could place properly).

The only thing I wasn't able to work out satisfactorily is setting the cell size. I wasn't able to have ArcMap do this while performing the mosaic, it would have to be a totally seperate step, which ended up being too time consuming.

This looks like a great tool but I can't seem to get it installed. The setup runs fine but nothing shows up in ArcMap and doing the Tools>Customize>Add From File routine doesn't seem to work either. Any thoughts?

I don't know if you will see this comment because this post is 3 years old but I can't download your tool and was wondering if there was another way to download it. I see that you offer some through windows live but not this one. If you could help that would be great.

About Me

I'm Ben Slater, GIS Data Manager at Wetland Studies and Solutions, Inc., an environmental consulting firm in Northern Virginia. I received a B.A. in Geography from Virginia Tech in 1995 and worked as a GIS research assistant at Harvard
Forest from 1995 to 1999. There, I assisted in various academic studies, mostly centered around historic land use changes and their effects on the current environment. After that, I relocated to Northern Virginia (my point of origin) and worked at the Prince William County GIS department for 6 months. In January 2000, I began working as the sole GIS Analyst at Wetland Studies, then a small firm of about 20 people. Today, WSSI employs about 100 people, has 7 full time GIS employees, and has acquired Thunderbird Archeology. My work here consists of developing in-house applications (mostly centered around automated map-production), production cartography, database development and maintenence, intranet development, and whatever else needs doing.
